Curtailed choice to stay inside drunk by evening (8)
I believe the answer is:
twilight
'drunk by evening' is the definition.
'twilight' can be an answer for 'evening' (I've seen this before). I am unsure of the 'drunk by' bit.
'curtailed choice to stay inside' is the wordplay.
'curtailed' means to remove the last letter.
'choice' becomes 'will' (someone's will is their decision or choice).
'to stay' becomes 'tight' (I can't justify this - if you can you should believe this answer much more).
'inside' means one lot of letters goes inside another.
'will' with its last letter taken away is 'wil'.
'wil' placed into 'tight' is 'TWILIGHT'.
Can you help me to learn more?
(Other definitions for twilight that I've seen before include "Period of illumination when sun is just below horizon" , "nightfall" , "Period of gradual decline or obscurity" , "when the night's still young?" , "Partial darkness" .)
